Question

if the sum of two consecutive natural number is 31 then the smaller number is​

Answer 1

Answer:

15

Step-by-step explanation:

sum of two consecutive numbers=31

x+x+1=31

2x+1=31

2x=30

x=15(SMALLER)

x+1=15+1

=16(BIGGER)

Answer 2

Step-by-step explanation:

Let the first number be x

Then the second number is x + 1

It is given that their sum is 31

x + x + 1 = 31

2x + 1 = 31

2x = 31 - 1

2x = 30

x = 30 ÷2

x = 15

Thus, the two numbers are x = 15 and x + 1 = 16

Therefore, the smaller number is 15
